Richard M Stallman
We are not against the Open Source movement, but we don't want to be lumped in with them. We acknowledge that they have contributed to our community, but we created this community, and we want people to know this. We want people to associate our achievements with our values and our philosophy, not with theirs. We want to be heard, not obscured behind a group with different views. To prevent people from thinking we are part of them, we take pains to avoid using the word "open" to describe free software, or its contrary, "closed", in talking about non-free software.
